Must Be Tested
Certified Backflow Testers - NEW LIST FOR 2022
A backflow prevention device stops water from irrigation systems, hot tubs, pools, new construction or other sources of potentially impure water from flowing back into the public drinking water supply. The devices are required to be tested annually by a state certified tester and the paperwork submitted to the Water Authority by the date listed on each customer's bill. Due dates are also shown below.
The New York State Sanitary Code requires water suppliers to protect our water supply and prevent back siphoning or reverse flow of water from irrigation systems, hot tubs, pools, new construction or other sources that could connect non-potable water with the potable water supply.
Pursuant to the Code, Water Authority of Great Neck North regulations require residents to have their backflow devices tested annually by a certified backflow tester. Customers with an in-ground sprinkler system must test their rain gauge/moisture sensors annually as well. Click here for the Rain Gauge Moisture Sensor Certification Form.
It is the responsibility of homeowners and business owners to have their backflow tested and the certification(s) submitted to the Water Authority by the required due date.
A list of certified backflow testers can be accessed by clicking on the Certified Backflow Testers link above.
